We’re excited to announce the release of new DLP recommendations for unprotected sensitive information in Office 365. This insight-driven recommendation helps you keep your sensitive content secure when its stored and shared in Office 365 by informing you when there’s a possible gap in your DLP policy coverage – we even provide an “easy button” to turn on a customized DLP policy to keep that content protected.

To see the recommendation, visit the Office 365 Security and Compliance Center homepage at https://protection.office.com and look for the “Recommended for you” section on the right side. (If you don’t see it yet – click “+More”) If you have content that isn’t protected by one of our top 5 sensitive information types, you’ll see a breakdown of what kind of content was detected, and an option to “Get started” for more details.

@Dean Gross: Not yet i think, although @Adam Jung would know better 😁. Dlp is working on Exchange and SharePoint (including OneDrive for business and Office Groups). But i have not seen it working on Yammer. I do doubt if it will ever though.
